I have a liftmaster that will not close all the way and just "bounce" back for no apparent reason within a foot of moving. I have disconnected the door and tried it, and same thing. I looked at the sensors for obstructions and they are not blocked. I doesnt' seem to have anything to do with the setting on strength of lift or set. Any ideas?
I had it working properly after replacing the main gear. Then all of a sudden this happens. It seems somewhat random.
